Padlock with a timer?

So, I have this fantasy that involves setting up and enema, probably with a retention nozzle, then starting the flow and self-bondaging myself with a timer actuated padlock, set at time at which I know I can still take the enema, but it would cause some discomfort. A kind of no-escape until the time is up kind of thing. Problem is, I cannot find anything that is like a lock that you can set the timer on and have it open after the time runs out. Do these devices even exist? I think it could be possible to make one with Arduino, but that is too much electronics and they don't mix with water too well. Did anybody try something like this?

As far as I am aware there are no specific padlocks with timers on them. There are a few alternatives though. Amon them are:

1. Kitchen safe - designed like a cookie jar with a timer. You could potentially lock your key in this and set the timer to open when you want it to. The problem is restraining yourself in a way you can access the key without being able to disengage the enema gear.

2. Ice - this is what I use an had performed a few self bondge enema sessions using ice timers, both to release the keys to my restraints and also to release a series of graduating intensity enemas.

There are a few ways to use ice, the challenge is that it is never precise. The size or orientation of the ice can impact the release, as will the ambient temperature. Some experimentation beforehand will give you a ballpark timing figure but don't bank on it being repeatable. Then again, maybe the unpredictability could add a certain something to your predicament!

Happy to talk in more detail about ice releases if that's of interest.

See this old post of mine of you are interested in how to lock yourself up and STAY that way until your pre-prescribed time is up.

Ice time locks seem kinda cool (totally intended), but I am looking for something to keep me locked up for maximum 15-20 minutes, and possibly as little as 3 minutes. I am also contemplating the issue of being able to unlock myself after a time period while not being able to stop/adjust the flow. Such a simple idea, surprised it doesn't exist.

Switchablesusie, that is too evil and also waay too long of a time stretch for my purposes. But funny. Thanks for this.

Some years back there was a company by the name of Wattmaster (lol--for real) that produced such a timer...very compact (small) of approximately 3&1/2"x2"x2" & could be pre-set for any time sequence over a 24Hour period with 10Min on /off intervals recurring...Also referred to as a Sunset SWITCH.

Not sure I understand the problem you are staying here. Do you want to be able to adjust the flow once you are unlocked or not?

If you do want to stop the flow you can just have a secondary clamp that is open by default so the enema can flow whilst you are locked but you can close it once you are free.

If you want a 3 minute lock up I would just use a really Lon piece of string with the key tied to it. If you are only able to use one hand to pull it in you will be amazed at how long it can take. Will give you something to think about instead if the cramps!

Just hire a nurse!!! :-)
